Answer:
As with sea horses, sea dragon males are responsible for childbearing. But instead of a pouch, like sea horses have, male sea dragons have a spongy brood patch on the underside of the tail where females deposit their bright-pink eggs during mating.
 
        
             
        
        
        
Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
Explanation:
Water and carbon dioxide are reactants for photosynthesis. Chlorophyll captures sun's light energy and then plants chemically combine this with water and carbon dioxide to make glucose (sugar) and oxygen.
 
        
             
        
        
        
Answer:
- Organism A is most likely a herbivore
- Organism B is most likey a carnivore
Explanation:
Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores. 
- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B. 
Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE. 
- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on. 
 
        
             
        
        
        
The correct answer is D: I and II only. 
Viruses have protein capsids, which protect their genetic material. This capsid sometimes is covered by viral envelopes which have glycoproteins on their surface. Glycoproteins help in the process of binding to the host cell and infecting it. In this example, virus III has the structure of a bacteriophage and it does not seem to have glycoproteins. Bacteriophages use their tail fibers to attach to the bacterial host and inject their genetic material. On the contrary, viruses I and II have glycoproteins sticking out of their envelopes.
